Metallic Bonding Lecture

[245kenz]

so non-metal lose electron and metal dnt lose electrons?

[Papapodcasts]

@245kenz non-metals don't lose electrons. They pick them up from metals if they are bonded together. These elements that exist on their own such as O, pairs up with another O to form O2. Same with N, Br, etc. These are diatomic and form bonds with other same atoms when they are on their own.

[tineshraj9402]

@Papapodcasts yeah.. the diatoms form either a single bond, double bond or triple bond between the same types of atom. For example Oxygen form double bond with each other whereas Nitrogen form triple bond with each other and halogens form single bond with each other.

[245kenz]

is this a secondary topics or some of them learn in high school?cos some of them i never heard before.

but the metallic bonding is it shape like kind of rectangle that consist of slip plane in between the two bar that contain free electrons and positive ion,as they can also slide?why they slide?is it because they were hammered to diff shape?

[Papapodcasts]

@245kenz Exactly that. It's really a basic understanding about how a metal, on its own, deal with their electrons. Hope it helps you. Good luck with your studies.

[245kenz]

I thought metals lose the electron,move freely and they could able to conduct electricity as the electron is mobility?why is it they share electrons through bonding?

[Papapodcasts]

@245kenz Yes, but to whom will they lose the electrons to. It's a non-metal, but if it is a metal ONLY then they will not have any other atom to give those electrons to.

this was helpfull for me

[05alis]

WTF . I still don't get it . Help

[Coveristism]

Very cool video, it really helps alot but i have one question.. do the Mg complete it's octet rule?

[Tehmakerful]

Doesn't metallic bonding occur between to metals? Such as Mg2Sn?

[Papapodcasts]

@Tehmakerful that formula doesn't exist.

[Tehmakerful]

@Papapodcasts So a metallic bond is just one metal such as Magnesium letting its electrons go ? My teacher taught me that its between two metals which i dont really get. Please help ?

[jaja830]

@Tehmakerful there can NOT be a COMPOUND between two metals (unless there is a NON-metal in between) if they are two metals only, they are alloys, alloys are MIXTURES

[sickcombos]

ok what happens to the ions and electrons of Mg when they are liquid (melted)or in the gaseous state(boiled)?

they will again take their electrons back and become atoms?

[Papapodcasts]

@sickcombos The same thing would happen as it did when it was a solid. The only thing that will change is the state (solid to liquid) Their kinetic energy has increased allowing them to move more rapidly.

[sickcombos]

@Papapodcasts does carbon exist as seperate atoms?

[sickcombos]

@Papapodcasts ok what happens to the metal ions if i react them with chlorrine??

[sickcombos]

@Papapodcasts ok i saw that before reacting this Mg with chlorine for e.g. they will be neutral atoms not ions as i saw, plz explain to me?

like this i read :

that Na(s) + Cl(g), the sodium before reacting how it will be neutral or what?plz answer me.

[Celixa0]

Valency affects the strenght of the mettalic bond because the more the metal can contribute valance electrons to the metallic bond the stronger the metallic bond will be, so the stronger the metall will be.

[jbrothers34]

heys hello! how does valency affects the strength of the metallic bond?

[mh2blade]

hmm si if they share electrons.... why arent they covalent.....

[Papapodcasts]

Think about how the metal loses the electron to the non-metal. The two atoms are still within close vicinity of one another so their valence shell almost overlaps.  Check out from the 4:00 in my video: Electronegativity Part 1 - Note how ionic bonds form. They don't form distinct molecules but instead "formula units". It forms similar to a crytsal lattice configuration of Na and Cl's. I hope this helped. Happy holidays. Mr.P

[Sgater13]

cheers mate, need thi for my mock exams and i missed the lesson on it.

good video!
